Abstract

A water treatment system having a base assembly and a treatment assembly. The treatment assembly of the system may be configured to filter particulates from water. The base assembly may include a UV reactor operable to disinfect water for consumption.

First claim

The invention claimed is:

1. A display for a water treatment system, said display comprising:
first and second light sources operable to generate light, said first and second light sources being separated by a light source distance;
a graphic mask including a graphic element configured to allow passage of light;
an optical element having first and second light receiving surfaces operable to receive light respectively from the first and second light sources, the first and second light receiving surfaces being opposed by an optical element surface of the optical element, wherein at least one of the first and second light sources being spaced from the optical element surface by an optical element distance;
wherein the optical element includes a mask facing surface adjacent to the graphic mask and defined between a) at least one of the first and second surfaces and b) the optical element surface, wherein light received by the first and second light receiving surfaces reflects internally within the optical element with respect to the optical element surface and the mask facing surface; and
wherein the light source distance is greater than the optical element distance.

2. The display of claim 1 wherein light generated by the first and second light sources and permitted to pass through the graphic element appears substantially uniform with respect to a perspective of an operator.

3. The display of claim 1 wherein the light source distance is N times the optical element distance, wherein N is greater than 1.

4. The display of claim 3 wherein N is approximately 2.

5. The display of claim 1 wherein the graphic element of the graphic mask corresponds to an opening in the graphic mask.

6. The display of claim 1 wherein the graphic element of the graphic mask corresponds to a light transmissive portion of the graphic mask.

7. The display of claim 1 wherein the graphic element corresponds to a strip extending parallel to the optical element surface.

8. The display of claim 1 wherein the first and second light receiving surfaces are curved to substantially prevent redirection of light output respectively from the first and second light sources.

9. The display of claim 1 wherein the optical element surface is configured to reflect light in a scattering manner within the optical element.

10. The display of claim 1 wherein light escapes the optical element in response to encountering the mask facing surface at an escape angle of greater than 45° with respect to an area corresponding to the graphic element.

11. A water treatment system comprising:
a treatment assembly having a filter assembly that is capable of removing particulates from water;
a base assembly operable to discharge treated water to a point-of-use, the base assembly including a frame configured to support the treatment assembly;
the base assembly including a UV reactor configured to disinfect water by applying UV energy to water flowing through the UV reactor for disinfection, the UV reactor being fixedly coupled to the frame of the base assembly; and
a display operable to convey information pertaining to operation of the water treatment system, the display comprising:
first and second light sources operable to generate light, said first and second light sources being separated by a light source distance;
a graphic mask including a graphic element configured to allow passage of light;
an optical element having first and second light receiving surfaces operable to receive light respectively from the first and second light sources, the first and second light receiving surfaces being opposed by an optical element surface of the optical element, at least one of the first and second light sources being spaced from the optical element surface by an optical element distance;
wherein the optical element includes a mask facing surface adjacent to the graphic mask and defined between a) at least one of the first and second surfaces and b) the optical element surface, wherein light received by the first and second light receiving surfaces reflects internally within the optical element with respect to the optical element surface and the mask facing surface; and
wherein the light source distance is greater than the optical element distance.

12. The water treatment system of claim 11 wherein the filter assembly includes a replaceable filter medium, and wherein the base assembly is operable to removably couple to the treatment assembly.

13. The water treatment system of claim 11 wherein light generated by the first and second light sources and permitted to pass through the graphic element appears substantially uniform with respect to a perspective of an operator.

14. The water treatment system of claim 11 wherein the light source distance is N times the optical element distance, wherein N is greater than 1.

15. The water treatment system of claim 14 wherein N is approximately 2.

16. The water treatment system of claim 11 wherein the graphic element of the graphic mask corresponds to an opening in the graphic mask.

17. The water treatment system of claim 11 wherein the graphic element of the graphic mask corresponds to a light transmissive portion of the graphic mask.

18. The water treatment system of claim 11 wherein the graphic element corresponds to a strip extending parallel to the optical element surface.
